Evolution (Dark Matter‪)‬

Evolve or die.

Caught up in Dr. Cross's mysterious and brutal Multiverse cult, Shay must pretend to be a devoted cultist while secretly plotting her escape. There's a wrench in the works: Dr. Cross has the real Callie—and she doesn't remember anything about her old life. What's more, Dr. Cross plans to use Shay as the carrier for a new plague that will end humanity as we know it.

Meanwhile, Freyja seizes her chance to poison Kai against Shay. Can Kai bring his stepfather's crimes to light before it's too late?
